Department of Botany, Oberlin College, Oberlin, Ohio 5th May, 1943 Pollen Analysis Circular Number 1
FOREWARD. Because of the suspension of many scientific meetings and increasing hand- icaps to travel, the undersigned feels greatly the need of a freer interchange of in- formation among those who are interested in pollen analysis in this country. He is therefore ready to underwrite the preparation and mailing of two issues to those who may be interested, after which, if the response seems to justify it, Professor L. R. Wilson of Coe College, Cedar Rapids, Iowa, has indicated that he will be willing to underwrite to additional circulars, and Professor J. E. Potzger of Butler University Indianapolis, Indiana, two more. You are therefor cordially invited to submit brief notes and correspondence, in- dicating questions on which you would desire information and giving and information which may be of interest to your colleagues working in this field. - Paul B. Sears TOPICS FOR DISCUSSION. "Thinking over the uses that such a bulletin would be to me, the following items appear at the moment. (1) A discussion of conifer pollen iden- tification. (2) What species of tree, shrub, and herb pollen or spores should be recorded in the counts for certain types of studies? (3) How should these counts be published? Are graphs enough in these days of uncertain printing? (4) Fre- quently new pollen and spore material is needed and it might be secured through this medium. (5) Frequently I stumble on the identity of a common unknown fossil and the discovery might be shared. Also we might describe certain unknowns and ask for help in their identification. (6) Since the Erdtman bibliographies appear to be discontinued we need another means of keeping up that valuable work. (7) I would like to keep track of workers in the same field and know what they are doing." L. R. Wilson. DIRECTORY OF WORKERS. The following list is tentative and by no means complete. It includes a few names of colleagues who, while not engaged themselves in pollen anal- ysis, have demonstrated a lively interest in the subject. Some names have been omitted because the individuals are now engaged in other types of work exclusively and are not likely to resume pollen analysis. Names and addresses which should be included in future issues will be appreciated. Copies of this circular are being mailed to those here listed. Antevs, Ernst, The Corral, Globe, Arizona.

I have repeatedly tried the various special and improved methods of preparing peat for analysis without observing any advantage over the simple 10% KOH procedure that repays the additional labor. This likewise has been the experience of a number of students here, several of them unusually skilled technicians. I tried the use of alcohol long before it was described by Geissler, but found that it had a tendency to harden the gumlike floccules present in many kinds of peat and so aban- doned it. The only modification of my method that has worked satisfactorily here has been to collect the samples in stoppered bottles of alcoholic potash. From this material slides were prepared by gentle boiling in aqueous potash as usual and beautiful mounts obtained. I would welcome any suggestions as to possible sources of failure with the various improved methods. - P.B.S. A WORD FROM ABROAD. In view of the difficulties of communication with our colleagues in foreign countries, the following excerpts from a note written by H. Godwin, Bot- any School, Cambridge, may be of interest. Prof. Godwin has made major contributions to pollen analysis in the British Isles. . . "The post-glacial forest history of North America is taking shape! . . . It is useful to consider ecology as contribu- tory to the war effort: it comes in more than one might suppose at first. . . Do you hear any news of Erdtman's projected book: it seems held up a very long time?" --3-- GUNNAR ERDTMAN. One of the staunchest aids to the growing field of pollen analysis has been Erdtman's series of papers "Literature on Pollen Statistics and Related Topics." The last copy at hand is dated 940 and cites papers published in the bi- ennum 1937-1939. We can do no better service to this good friend and colleague, now shut off from us, than to bring the list up to date so farr as our own continent is concerned. Errors and ommissions in the followint list will therefor be welcome, against the time when this industrious and learned man can resume his regular acti- vities. Erdtman, but the way, is a musician, and carried his flute with him into the muskegs of northern Canada in the summer of 1930, doubtless hoping to millify the savage mosquitoes with the sweet strains of Swedish folk-music.
